Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wiring cable duct for accommodating and protecting wiring cables such as electric wires and communication lines arranged along a wall surface or floor in a room, as well as various sensors, and particularly a lid body that covers the wiring cables. The present invention relates to a wiring cable duct in which an openable and closable arrangement is provided.

[0002]

[Prior Art]

 In the conventional wiring cable duct, for example, as disclosed in the wiring cable duct described in Japanese Utility Model Laid-Open No. 59-126522, a support member having a substantially U-shaped cross section and the support member are provided. There is a lid that covers the opening of the support, and there is a support and a lid that are provided with engaging portions that engage with each other. The wiring cable duct is generally made of synthetic resin. Further, here, the engaging portions are formed by the elasticity of the synthetic resin so that the engaging portions do not unnecessarily disengage once engaged.

[0003]

[Problems to be solved by the device]

 However, in such a wiring cable duct, the lid is configured not to open unnecessarily due to the engaging force of the engaging parts once engaged, and once the wiring is housed, the wiring is re-installed. There was a problem that it took a lot of time to re-do it. Further, since the wiring cable duct is generally formed of synthetic resin, there is a problem in that the lid and the engaging portion of the support are damaged when an unnecessary force is applied when opening the lid. there were.

Therefore, the present invention is a duct for a wiring cable devised to solve the above-mentioned problems of the conventional product, and an object of the present invention is to provide a duct for a wiring cable whose lid can be opened and closed. To do.

[0005]

Means for Solving the Problems The present invention has been devised in view of the above, and a bottom portion and side portions extending from the bottom portion at a substantially right angle are formed in a substantially U-shaped cross section, and a tip portion of the side portion is formed. A lid body having a support body provided with an engagement portion and an engagement portion arranged so as to engage with the engagement portion and covering an opening provided along the longitudinal direction of the support body. In the wiring cable duct, the wiring cable duct is characterized in that one or both of the surface edges of the lid body is provided with a protruding portion that is continuous along the longitudinal direction.

The protrusion of the lid used in the present invention has a predetermined length and is projected at the same angle as the outer surface of the lid or at a predetermined inclination angle. The size and angle can be changed as appropriate as long as the operator can pull the protrusion in the direction opposite to the support (the direction in which the lid is detached from the support). Further, if the protrusion is provided along one of the edges of the lid along the longitudinal direction, the engaging portion of the edge on the opposite side of the lid is used as a lever axis. The lid can be opened freely, but it goes without saying that the same effect can be produced by providing it on both edges of the lid. The material of the protrusion may be the same as or different from that of the lid, but the same material is preferable in manufacturing.

Further, as the engaging portion used in the present invention, any conventionally known engaging means as long as the lid portion and the supporting portion do not separate from each other even when receiving a force in the direction of opening the lid. There is no problem even if one of them is used, for example, one having protrusions in the direction of disengagement from each other, one consisting of a concave portion and a convex portion that engage only when the lid body and the support body are engaged, and one of There is one that wraps the other and engages with each other.

[0008]

[Action]

 According to the present invention, since the protruding portion is provided so as to extend substantially along the longitudinal direction at one or both end edges of the lid of the wiring cable duct, the protruding portion and this protruding portion are Can freely move the lid body to open the opening by using the engaging portion on the opposite side edge as a lever axis.

【Example】

 Hereinafter, a first embodiment according to the present invention will be described in detail with reference to the drawings. 1 is a perspective view showing a first embodiment of a wiring cable duct according to the present invention, FIG. 2 is an explanatory view showing a II cross section of the wiring cable duct of FIG. 1, and FIG. It is explanatory drawing which shows the effect | action which opens and closes a support body and a cover body.

As shown in FIGS. 1 and 2, the wiring cable duct according to the present embodiment is formed in a substantially U-shaped cross section from a bottom portion 10 and two side portions 11 and 11 and has an opening portion along the longitudinal direction. A main part is formed by a support 1 having the above and a lid 2 that covers the opening along the longitudinal direction. The wiring cable duct has an action as a wiring cable duct by wiring an optical cable or an electric wire in the space formed by the support 1.

An engaging portion 12 is provided at the tip of each of the side portions 11 and 11 as an engaging protrusion that faces the outside of the support 1, and an engaging portion 20 is provided near the edge of the lid 2. Are arranged as engaging projections whose inner ends are bent inward. A projecting portion 21 is continuously provided along the longitudinal direction at one edge of the lid body surface portion of the lid body 2. Reference numeral 13 in the drawing is a partition plate for partitioning the opening. Although not shown, the wiring cable duct has the bottom portion 10 in contact with a wall or floor, and the lower portion 10 is penetrated by a wood screw or the like to be fixed to the wall or the like.

The lid body 2 of the wiring cable duct according to the present embodiment is attached to and detached from the support body 1 through the steps shown in FIG. 3 as follows.

In the wiring cable duct in the engaged state shown in FIG. 2, when a force is applied to the protruding portion 21 of the lid body 2 in the arrow A direction in the figure and a force is applied to the side portion 11 in the arrow B direction. The engagement is released by the elasticity of the engaging portions 12 and 20 themselves on the side where the projecting portion 21 is not disposed, and the state is moved to the state shown in FIG. After that, the engagement between the engaging portions 12 and 20 on the side where the protruding portion 21 is not disposed is also released, whereby the support body 1 and the lid body 2 are separated. It is needless to say that the above operation can be reversed to attach the lid body 2 to the support body 1.

In the above embodiment, since the protrusion is provided in the vicinity of the lid, the lid can be easily detached from the support, whereby wiring is once performed in the space inside the support. The cable can be easily re-routed, and the lid and support are not damaged when the lid is opened.

A second embodiment according to the present invention is shown in FIG.

The wiring cable duct according to this embodiment is one in which the engaging portions 12 and 20 of the first embodiment are rounded.

In the embodiment described above, since the engaging portion of the first embodiment is more rounded than the engaging portion of the first embodiment, the lid can be rotated more easily using the engaging portion as a rotation axis. Therefore, the lid can be attached and detached more easily.

[0018]

[Effect of the device]

 According to the present invention, since either or both of the surface edges of the lid body are provided with the protruding portions that are continuously provided along the longitudinal direction, the lid body can be easily detached from the support body. With this, it is possible to easily re-route the cable once wired in the space inside the support, and further there is an effect that the cover and the engaging portion of the support are not damaged when the cover is opened.
